APPARATUS FOR STRETCHING FABRICS.

SPECIFICATION forming part of Letters Patent No. 280,489, dated July 3,1883.

(No model.)

10 jack; Fig. 3, an edge View of Fig. 2; and Fig.

4, a horizontal section thereof on the plane of the line 0 c, Fig. 2;Fig. 5, a detail face view of part of the supporting-rail.

This invention relates to certain improvements on the apparatus forstretching fabrics, which is described in Letters Patent No. 263,792,dated September 5,1882; and the invention consists in a novelcombination of the stretching-frame with a lower distending apparatus,as hereinafter described.

In the drawings, the letters A A represent beams fixed in the building,from which beams are suspended, by straps a a, rails or bars B. Thestraps a are attached to the ends of the rails B, so as to leave theupper edges of said rails free for contact with the rollers Z) of thecarriages O G.

D D are the upper bars, and E E the lower bars, of the stretchingapparatus, in or by which bars the fabric F is clamped or held. Theupper bars, D, are suspended by chains or links, or otherwise flexibly,from the carriages O, that ride on the rails B.

Instead of the tackle for stretching the fabric F that has heretoforebeen proposed, I eniploy the jack G, which is shown more clearly inFigs. 2 and 8. This jack consists of asuitable upper frame, 0, in whichis hung the the wheel f, meshes into the teeth of avertical ward whenthe lever h is vibrated on its ful crum. The framing 6 stands on fourposts, k 5

7c,between which the lower enlargement, l, of the rack j is guided-thatis to say, to the lower end of the rack j is fastened the plate Z, thatfits between the posts 70 and finds its guidance there, so that underthe strain of the stretching action the rack cannot be bent aside. Tothis plate I is secured the lower end of the rope or chain 111, theupper end of which is fastened to the lower bars, E, of thestretching-frame. Whenever the fabric F is to be stretched, the propernumber of these jacks G is placed beneath it, fastened to the floor bysuitable hooks or claws, and connected with the chains m, and then thelevers h are moved until these chains are stretched to the properextent, and with them the fabric F. Vhen the fabric has set or dried,the pawl g is lifted out of the wheel f, and the said wheel and itspinion can then be revolved in the opposite direction, so as to lift therack j and slacken the chains m and allow the disengagement of the jacksfrom the stretching apparatus and their conveyance to other stretchingapparatus, where they can be further employed.

I claim The combination of the movable stretchingframe D E, and devicesfor holding the same suspended, with the jack G, consisting of the postsis, bottom plate, Z, rack-bar j, wheel f, pawl g, lever h, and rope orchain m, for operation upon a fabric heldin said frame D E,substantially as specified.
